3 Agenda Perspective Sibling elements in managing storage of data Data Protection Tiering Archiving Integrating elements for economic value Summary

4 Data Protection A basic function --- and requirement How to do it is the big question Perceived as a necessary evil not a revenue generator for a company Costly opex and capex Unsustainable for most with capacity demand

5 Rethinking Data Protection Questions about data How is your data protected? What is required? How long does a recovery take? How long will data be retained? What are the compliance requirements? How much does this cost? Answer Re-examine: develop a new strategy Must be affordable and effective

6 Reasons for Protecting Data Protect from when a disaster occurs Second copy of information Copy on removable media at checkpoints Replicated copy of data At a remote location outside disaster area At a known point of consistency Can resume operations at remote location Time element is a matter of money and the type of protection that done

7 Reasons for Protecting Data Protect against data destruction / data unavailability Accidental deletion Corruption Hardware failure Recovery time is usually critical Frequency of protection Time to restore data Highly changing vs. static data difference in protection needs

8 Historical Method Backup Use backup software to capture data Write in encapsulated format Sequentially access Requires backup software to restore To tape systems Sequential media with % of unsuccessful restores 7 years before migrate to new generation drives Requires backup software To disk systems 5 to 6 years before migrate / replace systems

9 Historical Methods Continuing problems Time to get the backups done growing capacity Amount of space consumed for backups - generations Cost of technology transitions capital and migration Cost of backup software and administration Daily Incrementals Weekly Fulls Monthly Fulls Backup Cycles Quarterly Fulls Initial Full Backup Yearly Full Two Copies one is offsite

10 Disk-Based Approaches Data protection using disk-based storage technology Ongoing trend that is increasing Specialized devices Features of storage systems Data reduction technologies

11 Data Protection Storage System Local PIT Copies Archive System or Removable Backup Remote Replication (Sync or Async) Backup to Disk Remote Storage

12 Data Protection Still backup Use of disk and data deduplication technologies have become prevalent Still perceived as a tax Being done in isolation Improve the backup process Near-term objectives

13 Tiering Several types of tiering In the box Between different classes of storage Use of Flash / SSDs has crystallized attention for tiering Use within storage systems Use as an extension of cache Performance gains and costs managed compared to other solutions

14 Data Movement Storage System Tiering Within-the-Box Solid State Devices High-Performance Disks High-Capacity Disks Volume or sub-lun level May include virtualized external storage

15 External Tiering Primary Storage Secondary Or Bulk Storage Archive System Move or Migrate Between Tiers

16 Tiering In-the-box tiering Major performance boost Limit economic impact of costs of higher performance drives External tiering Economic benefits Performance management by placing data

17 Archiving Moving data that is not immediately required Less cost for storage Still retrievable and searchable Preserve --- for decades May require regulatory or business governance requirements Strict rules Integrity of data It s not backup

18 Archiving Primary Storage Secondary Or Bulk Storage Archive System Archive Based on Criteria or Selection

19 Archiving Different than backup One time operation move the data or store it directly in an archive Protection is done at time of archiving Multiple copies are made NO MORE BACKUPS of archived data

20 Probability of Access Access to Information 100 % Inactive or Fixed Content Information Primary Storage Secondary Storage Off-line Archive 0% 0-30 days Short-Term Data Protection days Long-Term Data Preservation 4-12 months 1 year +

21 Archiving Archiving controlled by policies criteria Age of information / last time used Type of data Owner Business criticality Size Space available

22 Archiving Typical actions for archiving generally associated with unstructured data Archive and leave copies data to archive device and leaves original copy Archive and stub copies data and leaves a stub that has attributes and when access will retrieve file Archive and delete moves data and deletes from the file system. Alternate path (link) may be set to the archive system for access

23 Archiving Economic impact probably the greatest potential for cost savings Data stored on less expensive technology Storage for longer term Free up capacity for other data Meet other demands compliance / governance

24 Integrating the Elements Coordinating the implementation of data protection, tiering, and archiving Greater economic impact Are interrelated Operational workflow implications for each Need to be coordinated

25 Integrating Data Management Elements Archive Based on Criteria In-box Tiering Primary Storage External Tiering Backup Secondary Or Bulk Storage External Tiering Archive System Remote Replication (Sync or Async) Backup to Disk Remote Replication (Async) Remote Replication (Async) Remote Primary Storage Remote Secondary Or Bulk Storage Remote Copy Archive System And / or removable copy

26 Summary Integrating the elements: Needs to be part of overall storage strategy Meet demands Protect data Requires understanding of technologies and techniques
